NOTES
1Defined as the average of the input voltages at the low to high and high to low transition points. Refer to Figure 6.
2Defined as half the magnitude between the input voltages at the low to high and high to low transition points. Refer to Figure 6.
3+V
S must be no lower than (VLOGIC –0.5 V) in any supply operating conditions, except during power up.
All min and max specifications are guaranteed. Specifications shown in boldface are tested on all production units at final test.
Specifications subject to change without notice.
(Operation @ 25 C and +VS = 15 V, –VS = –15 V, VLOGIC = 5 V unless otherwise noted.)
